Forsett's super-frustrating to own given Seattle's inexplicable loyalty to Jones. Even so, of those four, I'd start him this week.
For the second spot, it gets tougher. Harrison isn't a bad play against a now-unintimidating Pitt defense, but that's probably the worst match-up of the bunch. Brown could get some playing time if Houston goes up early, but he's definitely worth more in PPR than standard scoring. Norwood is only worth a start if Turner sits obviously, and I have a feeling Atlanta's gonna be passing most of the game to catch up to NO. Lynch has been playing fairly well lately and gets a decent match-up with KC.
In the end, I start Brown and Forsett; consider plugging Norwood in for either (although Forsett is sharing carries, so he'd be the first to go in my opinion) if Turner sits.
